The visibility section of the wiki link suggests that they may be resilient. They are printed using a low visibility color (light shade of yellow) which can be made visible via post processing. While they do note using a high resolution scanner, I suspect that could be made less important by building redundancy into the MIC, a la how QR codes can function well despite having portions be damaged or missing.
- Someone1234 4y agoI wonder if anyone has looked at the leak for a MIC/yellow dots. It contains a color channel (see highlighting) so it is plausible it could, even if re-scanned.
- micromacrofoot 4y agoI quickly isolated the blue channel of the document and ramped up the saturation (which should emphasize yellows), but I can't find any obvious dots (even at 10x zoom). AFAIK it's not the only method in use though, just the most well known.
- nullc 4y agoI checked it and failed to find any. Though if it was scanned from a color print its very likely that they were there in the paper version-- they just may not have survived scanning.
